row and the gage of the wire being, also, Fadualted from the largest of which the argcet rings are formed to the smallest of wh ch fihe smallest rings are formed. The casing or armor i constructed as just dcsicrihed is in the form of a continuous band and naturally assumes the form of what is commonly called a straight side casing, which may be mounted on the folly 3 of a wheel and locked and held securcl thereon hy the clam rings 4 in the usua manner. As a means or retaining the casing or armor 1 inv its natural form and, also, for, holding same on the felly 3 of the wheel, as well for strengthening same, each row of rings 2 oh its rim is provided with an annular core 5, which may he formed by passing a wire several times through the rings 2 in said row at the rim and then welding or otherwise securing the ends of the wire ti'igcthcr, or, if desired, each core may he formed of a small wire cable, or a. solid continuous ring (not shown in the drawings), or other suitable means.

The interstices between mutuallymdjacent' rings are designed to receive filling pieces, which latter are preferably in the form of planoconvcx metal disks 6 having convex outer feces and fiat or plane inner faces as depicted in Figs. 3 and 4, though, if desired, conczu'o-convcx or hell-shaped disks 7 having convex outer faces and concave inner faces as shown in Figs. 5 and (l, or disks like those (lisclosedin mv above-mentioned natcuts may he used. These filling pieces, like ihc rings 2, are graduated in size from the largest which fill the interstices between the rings in the middle of the trend to the smallest which fill .ihe interstices between the rings adjacent to lhe rim of the casing, and are held in place solely by the rings themselves, the lacter being'so closely interwoven as to require no extraneous retaining means,

The ohain-and-(lisk casing or armor l constructed as hereinabove described is not only strong and endurahle, hut possesses the qualities of flexibility and impcnetrahility chal; render it particularly well. adapted for antomol'iile tire casings, though it should he understood that this chain-anddisk fabric may he used in the manufacture of mesh purses and hugs, door-mats, conveyor belting, and for various other purposes.

In order to protect the inner tube 8 from lhe chain fabric, the inner wall of the casing or armor 1 is covered with e coating or lining 9 of a waterproof, flexible, and lubric composition, which constitutes the subjectmatter of myother application filed of even date and consists of rubber cement, a hydrocarbon, preferably benzene, and graphite thoroughly mixed together, preferably in the proportions of substantially equal parts of rubber cement and graphite and sufficient benzene to make the composition viscous so that it can be applied to the inner wall of the casing or armor by a brush or other suitable means (not shown). When this composition is applied in a viscous state to the inner wall of the casing or armor 1 to form the coating or lining 9, it runs into and fills all the cracks, crevices, and interstices in the inner wall of said casing or armor and thereby so amalgamates with the chain-anddisk armor as to form as much an integral fabric as is rubber-coated canvas or other reticulated material. When this coating or lining dries or sets, it is irremovable and is most intimately associated with the rings and disks, due to the fact that it runs into all the interstices in the inner wall of the casing or armorwhile it is in a viscous condition, the outward pressure of the inflated inner tube 8 ali'ording additional means for preventing the coating or lining 9 frombecoming separated from the chain-and-disk fabric. This coating or lining 9 hardens sufficiently to prevent blowouts, and is rendered waterproof and flexible by the rubber cement present insame, while the graphite acts as a lubricating agent which prevents abrasion of the inner tube.

It will be observed that the outer wall of i the casing or armor 1, instead of being covered with rubber as in my above-mentioned patents, is left bare, whereby the metallic tread prevents thetire from skidding. As shown in the drawings, each ring 2 isformed of a piece of wire bent in an annular shape and having its ends 10 nearly abutting, and is arranged so that said ends are located in the inner wall of the casing or armor 1. By

'this arraugen'icnt, when the composition is applied to the inner wall of the casing or armor 1 to form the coating or lining 9 as hereinabove described, some of the composition enters between the nearly abutting ends 10 of the rings 2 and, when it dries or sets, retains the ends 10 of the rings in the inner wall of the casing or armor and prevents said rings from working around, with the result of preventing the ends 10 from becoming exposed in the outer wall of the casing or armor and, also retaining each ring in such position that only the middle portion intermediate the ends 10 thereof is exposed. This arrangement, in conjunction with the fact that the rings are formed of spring steel wire, increases the longevity and strength of the casing or armor 1-, as the ends 10 of the rings 2, being located in the inner wall of the casing or armor, are prevented from spreading apart which spreading would, obviously, be apt-to occur if the ends 10 of the rings were exposed in the outer wall of the casing or armor. It should located in the middle of the tread. If, howover, it is desired to form a casing or armor- 1 which will have a relatively fiat tread, it is only necessary to locate a plurality of annular rows of rings of the largest size in that particular-portion of the casing or armor.

In order to provide for longer wearing purposes and thereby increase the longevity of the casing or armor 1, the middle or exposed part of each ring 2 in the tread of same may be provided with a protuberance or raised lug 11, as depicted in Fig. 7, or it may be inade relatively thicker than the unexposedpart of same.

While, for the purpose of illustration, the

rings 2 are connected and interwoven in such manner as to form a casing or armor 1 of the straight side type, yet, it should be understood that the rings may be so connected and interwoven as to form a casing 0 or armor of the clencher type.

I claim 1. A fabric consisting of interwoven rings, and a coating therefor composed of a m xture of substantially equal parts of rubber cement and graphite.

Q. A tire provided with an outer casing consisting of chain fabric having filling disks inserted in the interstices, and a lining for said casing composed of a mixture of substantially equal parts of rubber cement and graphite.
